Duplicate INDEX entries of long standing

[Conrad J. Sabatier]

I've been seeing the following it seems like forever in my nightly
scheduled ports tree maintenance script output:

Starting rebuild of INDEX-10 at Mon Feb 13 03:52:55 CST 2012

Generating INDEX-10 - please wait..Warning: Duplicate INDEX entry:
gdb-insight-6.6 Warning: Duplicate INDEX entry: petsc-mpich-2.3.3.p0_6,1
 Done.

Rebuild of INDEX-10 completed at Mon Feb 13 04:10:29 CST 2012

Anyone know what's the story with these?  And/or how to get rid of them?
Are there any plans in the works to remove them from the ports tree, or
otherwise fix them?

Thanks!
